Linux pyrtlsdr no longer available – what can be used instead during installation of ezRA?
Admin
I collect data with free Linux PCs. I find my Windows 10 PC is running Python 3.9.4, which does not show a problem. I see available Win11 Python version 3.12…

Maths Ted uses to calculate galactic velocity in ezRA
Maybe your answer is explained at about https://www.youtube.com/watch?v=YXuPDJVRbd0&t=1892sor maybe starting back at https://www.youtube.com/watch?v=YXuPDJVRbd0&t=1083swhere I explain the tangential velocity method.The radius from the Galactic Center to the tangential gas cloud is…
In GNU Radio there is an AM demod block. If this wasn’t there what processes would be required to achieve same function?
AM demod looks simple on the surface, but under the hood it’s doing a couple of neat little tricks. If the built-in AM demod block vanished overnight, you’d rebuild it…
How do switch blocks and selector blocks in GNU Radio work?
These two get mixed up all the time in GNU Radio because they sound similar but solve slightly different problems. I’ll explain them intuitively first, then a bit more technically,…
I am looking for a GNU Radio flowgraph on Github or elsewhere that shows me how to incorporate ability to choose between SDRs whilst running the program.
Here are some open-source GNU Radio flowgraphs / projects on GitHub that you can study or adapt when you want to choose between different SDR hardware sources (e.g., RTL-SDR, USRP,…
Push button blocks in GNU Radio, and how to continuously display a variable state such as the one changed by a push button or other mechanism
Is there push button block in GNU Radio Companion? Yep — there is 👍 In GNU Radio (QT GUI) you’ve got a couple of button-style options, depending on what behavior…
Data .txt Files & Timelapse Video of Data Collection of comparison between ezCol.py & ezColGR (GNU Radio version) on LRO-H2(SCRT) using same 150cm dish, feed and SDR 24-25/1/2026
These are both relatively long integration times on the Intel i5 MiniPC used for this experiment. The numbers are not equivalent – in both cases I attempted to obtain an…
How to use GLon.py in ezRA (Easy Radio Astronomy)
ezRA’s ezGLon.py program studies cross sections of the Milky Way, along one Galactic Longitude (GLon). ezRA’s ezGLon.py program processes *GLon.npz files. Above, the ezGLon.py program errored because it found *Gal.npz…

Converting a Python GNU Radio block into C++
Converting a Python GNU Radio block into C++ is very doable, but it’s not a mechanical translation — you’re moving from a runtime-defined block to a compiled, typed one that…
